Comparative literature mainly uses qualitative research methods and rarely utilizes quantitative methods. The possibility of applying digital humanities in comparative literature has been fully verified, and the application of new methods will provide new perspectives for research.In view of this,digital humanities can be introduced to research in the field of comparative literature. The research results show that: the presentation of research topics in the field of comparative literature broadly extends from the three core areas,and a series of new hotspots,such as fusion, have gradually evolved in a linear manner over time; authors in the field are closely related and have a clear core author group ; the major documents are characterized by their focus on translation and world literature ; the U. S. has the strongest research capacity,and emerging countries,such as Poland, Romania and Slovakia,are also developing rapidly ; and the U.S.,China and Brazil exhibit obvious trends towards international cooperation,while emerging countries remain reliant on domestic author cooperation.国家社会科学基金重大项目“健全国家大数据主权的安全体系研究” (18VSJ034);教育部人文社科重点研究基地重大项目“大数据资源的制度规制和国家治理研究”(17JJD870001

    The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
